Javascript Calculation didn't Work for First-time Appearance

Question

Hi, I have calculations in my JavaScript code not working when the first time I visit the page. But when I revisit the page by hitting “Back” or “Next” and coming back to the page, the calculations results will appear. I attached two screenshots, one is what it looks like when I visit the page first time, one is what it looks like when I revisit the page. Could someone help me figure out the potential issues and solutions? Thank you so much! Here is my interface:Round 1 FeedbackInvestment return this round: ${e://Field/investment_return_this_round}Investment return based on your own strategy this round: ${e://Field/investment_return_own_strategy}Investment return based on AI-suggested strategy this round: ${e://Field/investment_return_ai_strategy} Here is my JavaScript:Qualtrics.SurveyEngine.addOnload(function() {    // Retrieve input values for Decision1, Decision2_1, and Decision2_2    var decision1 = parseFloat("${q://QID1453/ChoiceTextEntryValue}");    var decision2_1 = parseFloat("${q://QID1492/ChoiceTextEntryValue/5}");    var decision2_2 = parseFloat("${q://QID1492/ChoiceTextEntryValue/6}");     // Initialize variables for investment returns    var investmentReturnThisRound, investmentReturnOwnStrategy, investmentReturnAIStrategy;     // Calculate "Investment return this round" with conditional logic    if (decision1 === 100) {        investmentReturnThisRound = round(            decision1 * 0.8306 * 0 +            decision1 * 1.0028 * 1,            2        ) + "%";    } else if (!isNaN(decision1) && !isNaN(decision2_1) && !isNaN(decision2_2)) {        investmentReturnThisRound = round(            decision1 * 0.8306 * 0 +            decision1 * 1.0028 * 1 +            (decision2_1 * 0.8306) +            (decision2_2 * 1.0028),            2        ) + "%";    } else {        investmentReturnThisRound = "Invalid Input"; // Handle invalid cases    }     // Calculate "Investment return based on your own strategy this round"    if (decision1 === 100) {        investmentReturnOwnStrategy = "N/A"; // Show "N/A" when decision1 equals 100    } else if (!isNaN(decision1) && !isNaN(decision2_1) && !isNaN(decision2_2)) {        investmentReturnOwnStrategy = round(            100 * ((decision2_1 / (100 - decision1)) * 0.8306) +            100 * ((decision2_2 / (100 - decision1)) * 1.0028),            2        ) + "%";    } else {        investmentReturnOwnStrategy = "Invalid Input"; // Handle invalid cases    }     // Calculate "Investment return based on AI-suggested strategy"    investmentReturnAIStrategy = round(        (0.8306 * 0 * 100) + (1.0028 * 1 * 100),        2    ) + "%";     // Set Embedded Data for displaying values in the survey    Qualtrics.SurveyEngine.setEmbeddedData("investment_return_this_round", investmentReturnThisRound);    Qualtrics.SurveyEngine.setEmbeddedData("investment_return_own_strategy", investmentReturnOwnStrategy);    Qualtrics.SurveyEngine.setEmbeddedData("investment_return_ai_strategy", investmentReturnAIStrategy);     // Helper function for rounding numbers    function round(value, decimals) {        return Number(Math.round(value + "e" + decimals) + "e-" + decimals);    }}); First time visit this pageCalculation works when I revisit the page
